Bangkok airport certainly is and after a long time of criticism trying to work out some problems that it is facing but for me it is ignoring the most important and the one that causes most irritation. I am talking about immigration. Passport control is always in chaos. There are 2 main rush hours in the airport still struggles with very slow passport control officers and less than 50% of the pass-checks open. 55minutes on departure and 45min at arrival is just unacceptable. The marketing of Suvarnabhumi is visible in the Thai media as they are achieving faster service and with a smile. I reckon most of the passport control officers flanked the lessons. All I see at the pass desk is stickers and advertising of who supplied the camera, who supplied the air freshener etc. So if I can give passport control any grade lower than zero, I would. Otherwise security was better and faster, the so-called duty free has lost my attention for the last 6 years so I just go through, still nothing of interest close to the gates and the place there looks like a barren desert, waiting at gates much better with padded seats giving the place a better look, always prepare for long walks at arrival to the passport controls.
